Site Filtering

The OT Source family uses the APM Site Filter Control. When an OT Source record is created, it is assigned as Global. If the record is not reassigned to a specific site, then the user will always see the global record. For more information, refer to the Site Filtering section of the documentation.

Note: Only a Super User can modify the site assigned to an OT Source record. A user can modify the site assignment to a newly created connection record. However, once the user saves the system, it is no longer modifiable by a non-super user.

The OT Source is used to facilitate the transfer of records from your Process Historian server into APM. Specifically, Source Tags are transferred into APM. The records that are associated with the data source are assigned to Global when they are initially transferred into APM.

The content Maps are foundational records that are used to map Source Tags to Equipment, Functional Locations, Health Indicators, and/or Policy Instances. The content Maps will inherit the site of the asset within the record.
